Amabhuleki resistorszingeniswa ohlelweni lokulawula izinjini ukuvimbela ukulimala kwehadiwe kanye/noma ukwehluleka ukuphazamisa ku-VFD. Ziyadingeka ngoba kweminye imisebenzi injini elawulwa yi-VFD isebenza njengejeneretha futhi amandla ageleza aye ku-VFD kunokuba aye enjini. Injini izosebenza njengejeneretha noma nini lapho kunomthwalo owenziwe kabusha (isb., lapho amandla adonsela phansi ezama ukugcina isivinini esiqinile ngenkathi isheshisa ilifti lapho iyehla) noma lapho idrayivu isetshenziselwa ukwehlisa injini. Lokhu kuzobangela ukuthi i-voltage yebhasi ye-DC yedrayivu inyuke, okuzoholela ekwehlulekeni kokugcwala ngokweqile kwedrayivu uma amandla akhiqizwayo engahlakazwa.

Kunezindlela ezimbalwa eziyisisekelo zokuphatha amandla akhiqizwa injini. Okokuqala, idrayivu ngokwayo izoba nama-capacitor athatha amanye amandla isikhathi esifushane. Lokhu kuvame ukukwenzeka lapho kungekho mthwalo owenziwe kabusha futhi ukwehla ngokushesha akudingekile. Uma amandla akhiqizwe engxenyeni ethile yomjikelezo womsebenzi emakhulu kakhulu kudrayivu iyodwa, isinqanda ukubhuleka singethulwa. Ii-braking resistorizokhipha amandla engeziwe ngokuyiguqulela ekushiseni kusici esiphikisayo.

Okokugcina, uma amandla okuvuselela enjini eqhubekayo noma enomjikelezo womsebenzi omkhulu, kungase kube usizo kakhulu ukusebenzisa iyunithi yokuvuselela esikhundlenii-braking resistor. Lokhu kusavikela i-VFD emonakalweni wezingxenyekazi zekhompiyutha kanye nokungasebenzi kahle okubi, kodwa kuvumela umsebenzisi ukuthi athwebule futhi asebenzise kabusha amandla kagesi esikhundleni sokuwachitha njengokushisa.
